Delta says the app was created in partnership with engineering company BCI. It also enjoys algorithms from the National Center for Atmospheric Research.

Remarkably, its data is even customized according to the type of plane. Bigger planes are affected by turbulence differently from smaller ones.

Delta claims this information is far more useful to pilots than the more common PIREPS system, which presents the pilots with information from planes that flew earlier in the day.

The result is that turbulence is more easily prepared for and avoided -- though there's no way to always get around it.

Nature's a little bigger than we are.

Darren Murph at the Points Guy says a Delta pilot gave him a demo of the app. The pilot explained how much more accurate the information was, which allowed the pilots and the cabin crew to prepare more thoroughly.

The biggest question, naturally, is whether frequent Delta flyers have noticed that their flights have been largely smoother.
